  Yes but depending on what Uber do with the technology it might be of no use to anyone else. The technology also depends on contacting servers which have information about the local 3D topology which implies that it is unlikely to be useful globally without someone wanting to be paid for the service. As an alternative, phones might start using the dual frequency L1+L5 technology which Broadcom announced last year to detect the reflected signals without relying on an external service with knowledge of the local topology. https://www.broadcom.com/products/wireless/gnss-gps-socs/bcm47755 https://www.broadcom.com/products/wireless/gnss-gps-socs/bcm... https://news.ycombinator.com/item?id=15308771 https://news.ycombinator.com/item?id=15308771

    Google and Apple have that urban topology info too. That’s 99% of phone mapping API users covered.
